AMC Eagle

Automatic transmission fluid capacity & service interval

AMC Eagle automatic transmission fluid capacity ranges from 3,8 to 8 liters. Service intervals include checks at 6000, 8000, and 12000 km, and changes at 24000, 44000, and 48000 km. The data covers 7 configurations.

Additional Notes

  • The AMC Eagle 151 shows a capacity jump between model year groups: the 1981-1983 configuration lists 3.8 liters, while the 1984-1985 configuration lists 8 liters. A 3.8-liter figure typically reflects a partial service fill, covering only the fluid drained during a pan drop, whereas 8 liters is more consistent with a full overhaul or dry-fill capacity.
  • The Eagle 258 for 1981-1983 carries both capacity values within a single row, specifying 3.8 liters up to 1982 and 8 liters from 1982 onward. This mid-range transition within a single engine designation points to a running production change in the transmission unit or service procedure during that period.
  • The Eagle 258 in its 1980 configuration shares the 3.8-liter capacity with the early 151 and early 258 entries, but carries a shorter change interval of 24,000 km / 15 months compared to the 44,000 km / 28-month interval applied to the 1981-1985 258 entries under normal use.
  • From 1984 onward, the Eagle 258 retains the 8-liter capacity established in the 1982 production change, with the 1984-1985 entries continuing the 44,000 km / 28-month change interval under normal use conditions.
  • The 1986-1988 Eagle 258 introduces a revised check interval of 12,000 km / 7 months under normal use, compared to the 8,000 km / 5-month check interval applied to all earlier model year entries. The change interval also extends slightly to 48,000 km / 30 months.
  • For the 1986-1988 Eagle 258, a separate severe-use specification is listed alongside the normal-use entry. Under severe conditions, the check interval tightens to 6,000 km / 4 months and the change interval shortens to 24,000 km / 15 months, while the 8-liter capacity remains unchanged between both use conditions.
  • Severe-use classifications in automatic transmission service generally account for operating conditions such as frequent towing, stop-and-go driving, or sustained high-temperature environments, all of which accelerate fluid degradation. The 1986-1988 258 severe-use change interval of 24,000 km / 15 months is exactly half the normal-use interval of 48,000 km / 30 months.
